Display (as a row) the Count of values in columns of a visualization

[acbox12]

Hello, say that I have a matrix visualization like this:

Date                  Speed over 50mph                  Age over 20

9/7/16                      66mph                                       25

9/8/16                      77mph                                            

9/10/16                    55mph                                       30

I want: 

Date                  Speed over 50mph                   Age over 20

9/7/16                      66mph                                       25

9/8/16                      77mph

9/10/16                    55mph                                       30

Count                         3                                               2

Basically, I'm trying to easily present specific stats, while also tracking the amount of times they occur. How can I add this last "Count" row to the matrix? The "total" function just adds up the values of the column instead of counting them. Is there another way of doing this?

@acbox12,

Instead, you may consider using UNION Function to add a calculated table.
